Iyo wunvise 'valve cage', niba utekereza ko ari inzu ikomeye kuri trim, ntabwo wibeshye, ariko wabuze icyo usobanura. Nintwari itaririmbye isobanura kugenzura, kuramba, kandi kenshi, imiterere ya valve yose mubikorwa bikomeye.
Imyumvire yibanze hamwe nukuri kubintu
Ibintu byinshi cyane bifata akazu nkibicuruzwa, byibanda gusa kubintu bito. Iyo ni inzira yihuse yo gutsindwa imburagihe. Akazu ntigahari gusa kugirango gafate ibice; nikintu cyibanze kiyobora urujya n'uruza, kugenzura umuvuduko, no gufata igice kinini cya cavitation nisuri. Nabonye indangagaciro zananiranye kuko trim yari Inconel 625 ariko akazu kari 316SS isanzwe yogejwe mumezi atandatu, hasigara icyuma cyiza rwose.
Aha niho ibishingwe hamwe nogukora ibisekuru byuwabitanze biba bidashoboka. Ukeneye umuntu wumva ko ubunyangamugayo butangirira gushonga. Isosiyete nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), hamwe nimyaka mirongo itatu mugikonoshwa no gushora imari, ibona ibi. Ntabwo ari ugukora ishusho gusa; nibijyanye no kugera kubintu byubusa, bidafite inenge muburyo bwa duplex ibyuma cyangwa cobalt ishingiye kumyanda kuva isuka yambere. Microscopic shrinkage cavity mumihanda ikomeye itemba nigisasu cyigihe.
Guhitamo hagati yibishishwa no gushora imari mu kato ni ibintu bisanzwe. Ku binini binini, bitagoranye cyane muri karubone cyangwa ibyuma-bito bito, ibishishwa birakomeye kandi birahenze. Ariko iyo uhuye nigishushanyo mbonera cyinshi cyo kurwanya cavitation cyangwa urusaku ruke muri super duplex cyangwa Hastelloy, gushora imari niyo nzira yonyine yo gutuma ibyo bice byimbere bigenda neza kandi neza nta mahirwe mubikorwa bya EDM. Ubushobozi bubiri bwa QSY hano ninyungu ifatika, yemerera ibyifuzo-byifuzo aho kuba inzira imwe-yuburyo bumwe.
Icyitonderwa ntabwo ari kwihanganira gusa gushushanya
Nibyiza, nuko ufite amajwi yo gutora. Noneho umurimo nyawo uratangira. Ubusabane bwo guhuza hamwe na bonnet hamwe nugucomeka, ubunini bwibyobo bitemba, kurangiza kwimbere yimbere - ibi nibyo bitandukanya ibice nibikoresho byabigenewe. Kudahuza gato hano ntabwo bitera kumeneka gusa; itera umuvuduko udasanzwe, kwambara kutaringaniye, no guhambira uruti. Ndibuka urubanza rufite umuvuduko ukabije wo kumanura valve aho kuganira hamwe nubuzima bugufi bwa kashe byagarutsweho mu kato kari bore yari microne nkeya hanze, bigatuma icyuma cyicara kimwe.
Ibi ni byiza Imashini ya CNC ifasi, kandi bisaba ibirenze iduka ryimashini igezweho. Bisaba guhuza no gutegura igenamigambi ryubaha igice cyanyuma. Umukanishi akeneye kumenya ubuso bukomeye mugushiraho ikimenyetso no kuyobora bitandukanye nuburyo bwubaka. Amaduka akora ibihimbano gusa azabura izo nuances. Ubuhanga bwo gutunganya, kimwe nibyo QSY yerekana, nibyingenzi muguhindura casting nziza mubice byizewe, bikora neza.
Reka tuvuge kuri ibyo byobo bitemba. Gucukura icyitegererezo cyibyobo biroroshye. Gucukura icyitegererezo aho buri mwobo ufite umurongo uhoraho, udafite burr na hydrodynamic inguni kugirango igenzure coefficient (Cv) n urusaku? Ubu ni ubuhanzi. Gutanga ntabwo ari ibitekerezo; ni intambwe iteganijwe. Burr irekuye irashobora guhagarara, gutembera epfo, no guteza akaduruvayo. Njye namaze iminsi nkemura ikibazo cya erratic valve igenzura gusa nsanga agace gato k'icyuma kiva ku cyambu cyarangiye nabi cyacumbikiwe mu cyicaro.
Guhitamo Amavuta Dilemma: Birahuye
Impapuro zihariye zikunda kuvuza Alloy 20 cyangwa Monel nkumuti-byose. Ariko gutoranya ibikoresho kububiko bwa valve ni ibiganiro hagati ya ruswa, isuri, umuvuduko, nubushyuhe. 17-4PH irashobora kuba ikomeye kubwimbaraga no kwangirika kugereranije, ariko ni amahitamo mabi ya chloride ikomeza. Mu buryo nk'ubwo, ibinyomoro bishingiye kuri cobalt nka Stellite 6 biratangaje kuri serivisi zangiza, ariko imashini zayo ninzozi mbi kandi igiciro ni kinini - urabigaragaza gusa mugihe ubikeneye rwose.
Aha niho ubunararibonye bwibikoresho bitanga umusaruro. Iduka risanzwe rikorana na spekiteri - uhereye ku byuma bikozwe mu byuma no mu byuma bya karubone ukoresheje ibinyomoro bishingiye kuri nikel nka Inconel 718 - bikura mu nda. Barashobora gusubiza inyuma kurenza urugero cyangwa kuburira kwirinda munsi. Kurugero, mugukoresha gaze ikarishye (H2S ihari), kwerekana ibintu bikomeye-bidafite imiti ikwiye yo kuvura ubushyuhe bwa sulfide irwanya ubukana nigisubizo cyibiza. Akazu gashobora guturika bikabije. Umufatanyabikorwa ubizi agomba gushyira ibendera.
Ndibuka umushinga wibihingwa bya geothermal aho amazi yari avanze nubushyuhe bukabije, acide nkeya, na silika yahagaritswe. Twabanje kugerageza akazu gakomeye 440C. Yashize mu muyoboro utagira ishusho mu gihe cy'umwaka. Igisubizo cyari uguhindukira kuri nikel-chromium-boron ivanze hamwe nubushyuhe bukabije hamwe no kurwanya ruswa. Ntabwo yari kuri valve isanzwe BOM, ariko yari igisubizo cyubuhanga. Abatanga isoko bafite uburambe buhanitse bashoboza ibisubizo.
Kunanirwa nkumwarimu: Ikibazo cya Vibrating Valve
Amwe mumasomo meza aturuka mubintu bitagenda neza. Twari dufite igenzura rya valve kumurongo wamazi wateje imbere cyane. Imyenda yari akazu gasanzwe karanga uduce. Isuzumabumenyi ryerekanaga kunyeganyega gutemba, ariko umuvuduko wagereranijwe.
Tumaze gusenya, twabonye ikibazo. Ibibanza biri mu kato, nubwo bikosowe neza, byari bifite ubuso buke nkubuso burangije kuruhande rwabo aho gukorerwa neza. Ibi byaremye uduce duto cyane, twuzuye imivurungano isuka kumurongo usanzwe - umuhanda wa kera wa Kármán vortex - wahuzaga inshuro karemano yikizira ubwacyo. Akazu kari kuririmba ubwako kugeza gupfa. Igikosorwa kwari ukongera gukora imashini yimbere yimbere kugirango igere hejuru neza, isenya guhuza. Byanyigishije ko ku kato muri gazi yihuta cyane cyangwa serivisi ya parike, kurangiza hejuru yinzira zitemba ni ngombwa nka geometrie.
Ubu bwoko bwo gukemura ibibazo akenshi bugwa kubabikora. Ntibashobora gukora umusimbura gusa, ahubwo bafasha gusuzuma no gusubiramo igishushanyo? Birasaba umufatanyabikorwa, utekereza-injeniyeri aho gufata ibyemezo gusa.
Kwishyira hamwe hamwe nishusho nini
Hanyuma, akazu ka valve ntikigera ikora mu bwigunge. Imikorere yacyo ihujwe no gucomeka, intebe, uruti, hamwe na moteri. Akazu kakozwe neza ntacyo kamaze niba icyuma kidahuye nuyobora hejuru yacyo neza. Niyo mpanvu bimwe mubintu byizewe cyane-serivise zikomeye zituruka kubakora ibicuruzwa bagenzura ibicuruzwa byose bya trim stack, byemeza neza.
Kubatanga ibikoresho nka QSY, ibisobanuro birasobanutse: gusobanukirwa inteko ni urufunguzo. Bakeneye kubaza, Ni ubuhe buryo bwo gucomeka bujyanye? Nibintu bya parabolike, V-icyambu, cyangwa igishushanyo mbonera? Ibikoresho byo gutunganya akazu kahujwe nigikoresho kiringaniye kiratandukanye nicyicaro kimwe, cyashizwe hejuru. Gutanga ibipimo no kurangiza ibintu byinshi nyuma yubufindo nibyo bituma abaterankunga ba valve bagera kubikorwa byizewe, byateganijwe.
Mu kurangiza, kwerekana akazu ka valve ni imyitozo mubitekerezo bya sisitemu. Nibice byumuvuduko wibice, umuyobozi utemba, igikoresho kirwanya cavitation, hamwe nuburyo bwo kuyobora. Gufata amasoko yayo nkubuguzi bworoshye ibikoresho bidaha agaciro uruhare rwayo. Ukeneye isoko ifata ibyuma bya metallurgie, ikamenya gukora neza, kandi, cyane cyane, ikumva ibidukikije byubugome iki gice kigomba kubaho. Iri ni itandukaniro riri hagati yigice gihuye nikintu gikora.
